解决方案
问题一：

yum -y install gcc gcc-c++ kernel-devel //安装gcc、c++编译器以及内核文件 

问题二：

下载 ta_lib 依赖包

wget --no-check-certificate https://downloads.sourceforge.net/project/ta-lib/ta-lib/0.4.0/ta-lib-0.4.0-src.tar.gz

解压并编译安装

tar -xvf ta-lib-0.4.0-src.tar.gz
cd ta-lib
./configure 
sudo make 
sudo make install 

安装 TA-Lib

问题三： 配置 /usr/local/lib

sudo echo "/usr/local/lib" >> /etc/ld.so.conf 
sudo ldconfig
